Application filed lay 7, 1905. Serial No. $31,381.

To allwhomit may concern:

Be it known that 1, JOHN RILEY HALDE- MAN, a citizen of the United States, residing at Springfield, in thecounty of Greene and State of Missouri, have invented certain-new and useful Im rovements in Molds; and I do declare the to lowin tobee full, clear, and exact description 0 the invention, such as will enable others skilled in the art towhich it appertains to'make and use the same.

T mventlon relates to 1m )rovements 1n molds for forming concrete wa s, blocks, and 1 the like.

The object of the inventionis to provide a mold of'this character having-means whereby a veneering of fineror different kind of material may be formed on one or both sides of the wall orblock.

A further object is to provide a mold-havingmeans whereby the sides thereofmay be removedwithout disturbing the frame-work or-guidestuddin \Vith these ant i other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and articularly pointed outinthe appended claims.

In the accompanying drawings, Figure 1 is a perspective vlew of the mold showing the parts arranged in position for use, and illustrating the manner in'which one of the sides of the same is released and permitted to be moved away from the wall; Fig. 2 is a cross sectional view of theamold shown in Fig. 1, with the concrete veneering and the concrete block arranged therein; Fig. 3 is a detail perspective view of the partition for forming the veneering; Fig. 4 is a similar view of one of the sections of core blocks; Fig. 5 is a perspective view of a slightly modified form of mold for constructing cellar walls and the like and l ig. 6 is a detail perspective View of the inner side of one of the side boards of the mold shown in Fig. 5.

Referring more particularly to Figs. 1 to e of the drawings, 1 denotes the mold, which consists of the side boards, 2 and 3. 'To the outer side of the side boards, 2, is connected 3 a series or upwardly pro ectin supporting bars, d, the upper ends of whic i are preferably notched shown at 5.

nested a series of supporting bars, 6, the i the supporting hers, and-6, are connected To the outer side of the side board, 3, is pivotally con 'lhe upper ends of 1 together by removable crossbars, ,8, the ends of which are adapted to be engaged with the notched u per ends of the bars, 4.and .6, as shown. 'l hrough the notchedupper ends of the bars and'the ends of-the cross bars,.8, are formed alined apertures, through Which-are inserted fastening pins, 9, by means of which the cross bars, 8, are held in'placeiand theupper ends of the supportin barssecured together. The outer sides 0 the bars, 6, adjacent to their lower ends are formed with recesses, 10, the purpose of which will hereinafter appear.

In the lower edges of the side boards, 2 and 3, adjacent to the supporting bars, are formed notches or recesses, and insaid notches are arran ed transversely disposed supporting and c amping bars, 12,.sa1d bars extending across the lower side of the mold, -.and through said notches or recesses in theside boards. The ends of the bars, 12-, project beyond the outer sides of the side boards, and are provided with a recess oraperture adapted to receive clamping pins, 13, whereby the lower portions of the side boards of the mold are held in position. The upper portions of the side boards are held in osition by means of the cross bars, S,whic ;are secured to the 11 per ends of the su porting bars, 4 and 6, as liereinbefore descri ed.

In order to provide means for forming a veneering on one or both sides of the wall or block formed bythe mold, I providelone or 1 more thin partitions, 14, which correspond in size and shape to the side boards, and :are adapted to be arranged in the mold adjacent to the inner sides of one or both of said boards and are spaced a suitable distance from said inner side by means of flanges, 15. Hingedly connected to the upper edge of the partition, 14, is a cover strip, i6,..which is adapted to be ioldedover to one side or the other of the partition so that the space between the artition and the adjacent side beard may e closed while the concrete'is being placed between the partition and the opposite side board, thus preventingan-v. coarse material which forms t e inain'wall i rom enformed. in using themold, the larger space between the partition and the sideboard is first :lilled with coarse concrete to forinthe main body of the well, after which the finer 1 material which forms the veneer is placed between partitionand the o *pesite side i heard. After the veneering an, the coarse tering the space in which the veneering is material have been suitably tamped, the partition, 14, is carefully drawn out, thus per mitting the contiguous surfaces of the veneering and mold section of the wall to unite without mixing. is provided with a series of hand-holes, 17, whereby the withdrawal of the partition from the wall is greatly facilitated.

In order to form suitable air spaces in the framework of perpendicular studding is pref- I sary to employ erably provided to guide and hold the mold sections in per endicular .alinement when misled to form the successive sections of the wa When the arts of the mold have been assembled as s own in Fig. 1, and are inposition for use, the 0uter edges of the supporting bar, 6, are laced against the vertical studding which olds the mold in position while being filled. After the wall has become sufficiently set or hardened, the upper cross bar, 8, is disengaged from the upper ends of the supports, 4 and 9, and the pins, 13, are removed from the apertures 1n the bars, 12. The supporting bars, 6, are now turned or swung on their pivots in position to bring the recessed portion 10 thereof across the studding, thereby providing space which will per- Init the side board, 3, to which the supports,

6, are ivoted, to be moved laterally or away from t e side of the wall, after which the opposite side board is disengaged from the opposite side of the Wall, and the parts of t e mold are then ready to be raised to the position for forming the neXt layeror section of the wall.

In Figs. 5 and 6 of the drawings is shown a slightly modified construction and arrangement of the mold, the same being here shown as arranged for forming a cellar wall or similar walls wherein one side of the concrete wall enga es or is built up against an earth wall or ot er formation. When constructing a wall of this character, it is only necesone side board, 20, said board being he in position by means of a framework of vertical studding as clearly shown in Fig. 5 of the drawings The side board, 20, is spaced from the studding when arranged in position for use by means of pivoted spacing blocks, or bars, 21, said blocks bein provided on their outer edges with longitudinally disposed recesses, 22. The

blocks, 21, are pivotally connected to the between outer side of the board 20, midway e turned their ends, and are adapted to The cover strip, 16, 1

lengthwise of the board to bring the recessed portion thereof across the studdin thus roviding spaces which will permit t e side board 20 being drawn back away from the side of the wall to allow the board to be raised on the studding in the position for forming the next layer or section of the wall. In forming the wall in the manner just described, the same may be constructed with a veneering by the use ofthe partition, 14,

and in the same manner as described in connection with the first form of mold, and this form of wall may be also provided with core holes or dead air spaces by the use of the core blocks, 18, and connecting strip, 19, as previously described.

When using the mold for forming blocks, the side boards will, of course, be of shorter length than when forming a wall, and suitable means may be provided for closing the ends of the space between the side boards.

In other res ects the use of the mold in forming bloc s will be very similar to the tion of a wall.

In constructing a wall, the connecting channels formed by the core connecting strips, 19, are covered by strips of tarred paper to prevent the channels from being lled up when the successive layers of the wall are formed.

From the foregoing description, taken in use described in connection with the formaconnection with the accompanying drawing,

the construction and operation of the inven tion will be readily understood without requiring a more extended ex lanation.

Various changes in the orm, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Lettors-Patent, is:

1. In" a mold of the character described, the combination with the side boards of the mold, of means to sup ort the same in operative position, remova le partitions adapted to be arranged adjacent to the inner sides of the side boards to form a veneering on one or both sides of the molded structure, means to space said partitions from the side boards, and means on said partition to close said space, said means also serving to facilitate t e removal of the partitions, substantially as described.

2. A mold for forming concrete walls, comprising side boards, g destudding to hold the mold in its adjusted positions for forming a I erpendicular wall, supporting bars ivotal y connected to one of said side boar s to engage said studding, said bars having recesses formed therein whereby when turned out of engagement with said studdin will permit the side board of the mold to e moved away from the molded sec- -tions of thewall, substantially as described. 3. In a mold of the character described, the combination with the side boards of the mold, of means to support the same in operative position, remova le partitions adapted to be arranged adjacent to the inner sides of the side boards to form a veneering on one or both sides of the molded structure, and means to cover the space between said partition and the adjacent side boards when the main ortion of the mold is being filled.

4. n a mold of the character described, the combination with the-side boards of the mold, of means to support the same in an operative position, removable partitions ada ted to be arranged adjacent to the inner si es of the side boards to form a veneering on one or both sides of the molded structure, and a cover strip hinged to the upper end of said artition and adapted to cover the space Between the same and the adjacent side of the side boards to form a veneering on one or both sides of the molded structure, and a cover strip hinged to the upper end of said partition and adapted to cover the space between. the same and the adjacent-side boards whenv themain portion of the mold is being filled, said cover stri s having formed thereinhand-holes where y said strip serves as a means for withdrawing said partitions.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
